Simon nominates Boo Radley as the most enduring character from To Kill A Mockingbird, which inevitably leads to a discussion around Go Set A Watchman, a book neither of them has actually read. Darren's enduring characters are Death from Markus Zusak's The Book Thief and Christopher Boone from Mark Haddon's The Curious Incident of the Dog in the Night-Time, which leads to a discussion of 'otherness' in characterisation and the importance of empathy. And, of course, if you're interested you can watch the two talking heads to accompany the audio, if that's your thing.
